Hi,I have been looking at the DIY cellphone project and have decided to try and build a slightly modified one using a SIM900 module and a Atmega1284p-pu 40 pin dip package. I am new to the Arduino IDE and cannot download the board definition to enable me to select diy cellphone in the Arduino IDE. Can anyone help.

I tried to follow the instructions on your site and downloaded the files from Github. The hardware folder in the cellphone2 software folder was empty and I was unable to select the board from the Arduino IDE.

I built the phone this spring in a workshop done by a girl called Tricia, and it is really possible to do it. David C. instructed us on how to solder the thing. After that I learned a new thing that made everything easier to solder - The copper planes are quite big so the board needs to be preheated for an ordinary solder iron to be soldered. Preheating is the key. I bought a special heatblower that works from under the board, but anything similar should work.
